UNITED STATES PATENT OFFICE.

WILLIAM H. GRUBB, OF HANNIBAL, MISSOURI.

BUCK-SAW...

SPECIFICATION forming We of Letters Patent No. 290,042, dated December11, less.

' Application filed September 24,1883. (No mode To (ZZZ whom it mayconcern.-

Be it known that I, W. H. GRUBB, a citizen of the United States,residing at Hannibal, in

the county of Marion and State of Missouri, have invented certain newand useful Improvements in Bucl -Saws and I do declare the followingtobe a full, clear, and exactdescription of the invention, such as willenable others skilled in the-art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

Figure l of the drawings is a representation of this invention, and is aside view. Fig. 2 is a perspective view'of the tubular frame. Fig. 3 isa perspective View, showing the rings on the saw-blade.

This invention has relation to saws; and it consists in the constructionand novel arrange. ment of the saw-blade and saw-frame, as will behereinafter fully described, and particularly pointed out in the claimsappended.

'Referring by letter to the accompanying drawings, a designates aspring-frame of tubular metal, bent to receive the saw-blade b, which isprovided at each end with a loop, b. The loops are slipped overethe endsof the tubular frame, and a handle, a, is secured to one end of theframe in any suitable manner. This construction does away with theintermediate braces and the. tension mechanism for regulating the blade.The blade can be removed at any time for sharpening the sawteeth andagain sprung upon the tubular frame. Stop-bolts f are provided toprevent the loops from moving up on the frame, which is bow-shaped.Without the stop-bolts the blade would have a tendency to move up on theframe when in use.

The saw, having no intermediate braces, may be used to cut thickertimber than the ordinary saws, and it is cheaper, more simple, and moredurable than those ordinarily used.

I am aware that it is not new to construct a saw-frame of tubular iron,the same having been bowed and the saw-blade secured to its arms bymeans of clips, and therefore do not claim such construction, broadly;but,

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with a tubular bowed spring saw-frame, of asaw-blade having end loops sprung up on the saw-frame, substantially asspecified.

2. A tubular spring saw-frame provided with stop-bolts near its ends, incombinatlon with a saw-blade having loop ends slipped upon thesaw-frame, substantially as specified.

In testimony whereof I afixmy signature in presence of two witnesses.

WILLIAM H. GRUBB.
